Please check if the Trend Micro program is installed on your computer. Here's how:

Press the Windows key + R on your keyboard.

On the Run window at the bottom left of the screen, type appwiz.cpl.

On the Programs and Features window, look for Trend Micro Maximum Security.

If there is a Trend Micro Maximum Security on the list, you should have a Trend Micro icon on your desktop. You may double-click on it to access the main console. Otherwise, visit the link that Tom Emmelot posted above to reinstall the Trend Micro program.
